     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0016]    Referring initially to  FIGS. 1 and 2 , an example electronic book  10  is shown that can have, in one embodiment, a foldable configuration to mimic opening and closing a paper book. Specifically, the electronic book  10  may have a rigid lightweight plastic “cover” member  12  joined to a rigid lightweight plastic “back” member  14  along a hinge  16  for movement between an open configuration ( FIG. 2 ), wherein an electronic display  18  of the “cover” member  12  is exposed for viewing, and a closed configuration ( FIG. 1 ), wherein the display  18  is not exposed because it lies flush against the inside surface of the “back” member  14 . If desired, an input device  20  such as a keyboard and/or mouse or other cursor control/point and click device may be provided on, e.g., the “back” member  14 . 
         [0017]      FIG. 3  shows an example electronic book  22  that may not be foldable in contrast to the book  10  in  FIGS. 1 and 2 , it being understood that the book  10  shown in  FIGS. 1 and 2  may incorporate the features of the electronic book  22  shown in  FIG. 3  in, e.g., the “cover” member  12  of the book  10 . The electronic book  22  includes a lightweight portable plastic housing  24  bearing an electronic display  26  that may be a touch screen display. Accordingly, if desired the housing  24  may include one or more stylus holders  28  such as plastic clips for holding an elongated rigid typically plastic stylus  30 , e.g., vertically on the housing with respect to the “top” and “bottom” of the housing, for use in inputting signals on the display  26  when it is a touch screen display. Without limitation the display  26  may be a liquid crystal display (LCD), light emitting diode display (LED), or other appropriate electronic display technology, and may further include audio display capability, e.g., a speaker. 
         [0018]    Using the input device(s) above a person can enter signals to a digital processor  32  within the housing  24 . In turn, the processor  32  can access a tangible computer-reader storage medium  34  such as but not limited to disk-based storage and/or solid state storage to execute logic herein. Electronic book files can also be stored on the medium  34 . It is to be understood that the processor  32  controls the display  26  to present user interfaces including a list of titles stored on the medium  34 , command input elements to support the book-to-book communication set forth below, book text from files on the medium  34 , and when the display  26  is a touch screen display, an image of an input device such as a keyboard with which the user can input alpha-numeric signals using, e.g., the stylus  30 . 
         [0019]    In some embodiments the processor  32  may communicate with one or more wireless transceivers for purposes to be shortly divulged. In the embodiment shown in  FIG. 3 , the processor  32  communicates with a long-range wireless transceiver  36  and a short-range wireless transceiver  38 . Without limitation the short-range transceiver  38  may be a Bluetooth transceiver or other short-range high bandwidth transceiver technology and the long-range transceiver  36  may be a Wi-Fi transceiver or ultra wideband (UWB) transceiver or wireless telephony transceiver or other appropriate transceiver. 
         [0020]    Using, e.g., the stylus  30  or other object a person may select a “highlight” selector presented on the display  26  to highlight text that is present on the display to indicate its selection. Also, the person may enter handwritten notes in the “margins” of text presented on the display, with the processor  32  executing a handwriting recognition module stored on the medium  34  to generate and store electronic alpha-numeric characters representative of the handwriting in the relevant portion of the electronic book file. In this way, a person can annotate an electronic book or the below-described summary document with comments at the location in the book file to which the comments pertain. 
         [0021]    If desired, a thin keyboard  40  or other key entry device may be plugged into the e-book to communicate user input signals to the processor  32 . Also, an output port  42  such as but not limited to a universal serial bus (USB) port may be provided that can be connected to a printer to allow a user to print selected text under control of the processor  32 . Yet again, the processor  32  can wirelessly send data to a printer through, e.g., the short-range transceiver  38 . 
         [0022]      FIG. 4  shows that the processor  32  may present on the display  26  a user interface  44 , permitting the user to select, via, e.g., touch screen input with finer or stylus or keyboard input, a “summary page” function. This invokes summary document logic, an example of which is shown in  FIG. 5 . 
         [0023]    Commencing at block  46 , the processor  32  in response to a selection of the summary function creates a summary document, which may be a word processing document. Proceeding to block  48 , user selections of material including text and graphics in an electronic book are received as, e.g., the above-mentioned user highlights. When highlighted, the selected material may be made to appear in a different format or color code than the remainder of the material in the book. Or, a selection in an electronic book may be made by making “parenthesis marks” on the touch screen at the beginning and end of the selection. 
         [0024]    At block  50 , the processor in undertaking the summary function automatically transfers the selected information to the summary document. Block  52  indicates that the individual selected portions from the electronic book can be arranged or laid out in the summary document in sequential order, i.e., in the same order in which they appear in the electronic book from whence they came. Block  52  also indicates that each portion in the summary document can include location information useful for identifying respective locations in the electronic book in which the portions appear. The location information may include, for example, a page number from the electronic book on which the portion appears, a link to the part of the electronic book at which the portion appears, etc. If the link or page number in the summary document is clicked the processor  32  may automatically present on the display  26  the corresponding page from the electronic book. 
         [0025]    Proceeding to block  54 , the user may insert, by means of, e.g., a stylus or finger against the display  26 , additional personal study notes to the summary document. The user can export the summary document to a printer to print, as a summary page for their study to help them memorize and understand content. As mentioned above the port  42  shown in  FIG. 1 , which may be a USB port which accepts jump drive, can be connected to a printer, or the summary document can wirelessly print directly to the printer using, e.g., the short range transceiver  38 . 
         [0026]    If desired, a suitable user interface may be presented on the display  26  to enable the user to select whether additional material related to informational portions added to the summary document are to be searched and if so, how many results should be returned. Accordingly, if the user selects further search at block  56 , the processor  32  automatically initiates an Internet search request using at least one term or keyword in the portion in response to entry of the portion into the summary document. The keyword may be the first several words of text of the portion, for example. The processor displays “N” search results (by, e.g., listing hyperlinks with short titles of the top “N” results returned) to received in response to the search request. Internet communication may be established using the long-range transceiver  36 , and to execute the search the processor  32  may invoke a web browser to go to an Internet search engine, automatically entering the keywords into the search engine. 
         [0027]      FIGS. 6 and 7  illustrate that a user may be given the option to break this information/reading summary page into flash card style. As shown by the user interface  58  in  FIG. 6 , while in the summary mode function the processor  32  may present a list of sub-functions including “normal” summary mode (discussed above), or “break into flash cards” sub-function. When the user selects “flash cards” the processor may execute logic an example of which is shown in  FIG. 7 . 
         [0028]    Commencing at block  60 , each summary entry is organized into a respective flash card file. At block  62  user input is received skip the next flash card, hide a flash card, scroll to the next flash card, etc. Selected flash card(s) are displayed at block  64 . 
         [0029]    Accordingly, an example implementation may have scroll, next page/card button, etc. The user, when the user has memorized a particular “e Flash card”, he can “skip” or “temporary hide” that particular “e-Flash Card” and go to the next one. For difficult flash cards the user can set a “repeat mode” which causes a particular “e-Flash Card” to shuffle, automatically and randomly appearing on the display  26  at a later time. 
         [0030]    Additionally, a super list function may be provided for each book the reader reads. This “SUPER LIST” can include multiple bookmarks that the user inserts at desired parts of book or summary document files to help track key concept pages. Under each “item” it can show the key phrases/short summary phrase that the user can input himself, or show key phrases that the user has highlighted. For example, if a user read a technical electronic book months ago, and he starts to forget some details of a key concept, he can go to the “SUPER LIST” function to find that key concept he wants to review, and select the corresponding “bookmark”. The processor  32  in response immediately displays the bookmarked pages, and the user can read that key concept in context again. This will be extremely helpful, for example, during the few days before final exams, to review key concepts. 
         [0031]    Additional functionality may be provided. For example, the processor  32  may access a clock or timer to record how long a reader displays a page of an electronic book and to calculate an average display time. The user/reader can see if their reading speed improves over time. Every time the reader reads and article, he can set a hidden timer, which will calculate his reading speed. As result, this statistical information can be stored in the book  10 / 22 . The user can check over the course of the year, if his reading speed has improved or not. The book  10 / 22  may also come with useful free articles regarding reading/study methods, so that users can also learn how to read and study better. 
         [0032]    While the particular ELECTRONIC BOOK WITH ENHANCED FEATURES is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
