Check on rules for using the research facilities. Many places will not allow you to carry closed notebooks, brief cases, etc. into the research area. Many insist on pencils only, so you will not leave ink marks on the original documents. Comply with the rules and always thank the library and archives staff for their assistance, preferably in writing. The first edition of this book was well received and prompted Mr. Adams to continue his research for another fifteen years, which then became the revised and enlarged edition in 1969.
