We saw an outcome of poor ad revenue in December 2000, when AltaVista cut off its free Internet service because advertising revenue wasn't enough. The company added a subscription fee thereafter. In my library system, we needed fast answers to questions about our continuations titles and budget. Bitlocker gave us the power to manage our continuations information in a database that I designed. Our acquisitions unit replaced a card file with a database that tracks titles, prices, dates received, and anticipated dates of next editions.
Selectors can get lists by title, by vendor, or by anticipated due dates.
Also, fields can be preset for specific values that appear as pull-down menus. For one thing, you can add fields after the database has been created and you have entered data. Say you'rehalfway through entering 1,200 titles, and you realize that you don't have a field for the local bibliographic control numbers. One of the limitations to Bitlocker is that it's a flat database. Within that limitation, however, you can sort the database by any series of fields you choose and arrange the resulting report according to fields selected.
