Most publishers of academic and professional literature are considering or already using digital technology, in particular, create electronic versions of print publications, using different methods bring books to readers. Thus, in an attempt to direct contact with consumers, some publishers use specialized distributors OverDrive or DPS, while others work only with traditional libraries through such services as Netlibrary and Questia, controlling the use of their texts. In addition, libraries can use the publishing house as aggregators. For example, Book Services publishers of scientific journals Blackwell (since 2007 part of the Wiley) integrates platform for digital libraries with their own system ebrary Collection Manager workflow, allowing to search, sort and organize academic and scientific publications. By all indications, a breakthrough in the direction of the digitalization of content have been American publishers to make, but the issue of copyright protection hinders this process. Another limiting factor – the issue of control of revenues from the use of content available on the Internet in different countries. And today, the principle of "fair use copyrighted material," lets readers in the U.S.

receive only bibliographic data, plus a few short excerpts on the topic of search. In Britain and other European countries free search is possible only on the books with expired copyrights, otherwise access to the source is also limited. Of course, the leading publishers of electronic books and textbooks trying every way to stimulate interest in this product, and some have made this good result. John Wiley & Sons, starting with 300 titles in 2001 and today sells about 2,000 items in an electronic format. .
