For state library ebook statistics reporting purposes, here are the enki title and item counts as of as of June 30, 2017:
66,811 unique titles
70,222 copies (total count of items/units)
Just FYI to date, as of 9/26/17:
70,111 unique titles
73,736 copies (total count of items/units)
Please not, these totals follow the state library stat guidelines when counting number of units or copies. Any unlimited usage (always available) titles are counted as 1 copy. Any finite licenses are counted by how many licenses purchased. E.g. 1 copy 1 user, purchased 10 copies, that counts as 10 units in state library stats.
From the state library guidelines:
Electronic Books. E-books are digital documents (including those digitized by the library), licensed or not, where searchable text is prevalent, and which can be seen in analogy to a printed book (monograph). E-books are loaned to users on portable devices (e-book readers) or by transmitting the contents to the user’s personal computer for a limited time. Include e-books held locally and remote e-books for which permanent or temporary access rights have been acquired. Report the number of electronic units, including duplicates, at the administrative entity level; do not duplicate unit count for each branch. E-books packaged together as a unit (e.g., multiple titles on a single ebook reader) and checked out as a unit are counted as one unit.
Report the number of units. Report only items that have been purchased, leased or licensed by the library, a consortium, the state library, a donor or other person or entity. Included items must only be accessible with a valid library card or at a physical library location; inclusion in the catalog is not required. Do not include items freely available without monetary exchange. Do not include items that are permanently retained by the patron; count only items that have a set circulation period where it is available for their use. Count electronic materials at the administrative entity level; do not duplicate numbers at each branch.
NOTE: For purposes of this survey, units are defined as “units of acquisition or purchase”. The “unit” is determined by considering whether the item is restricted to a finite number of simultaneous users or an unlimited number of simultaneous users.
Finite simultaneous use: units of acquisition or purchase is based on the number of simultaneous usages acquired (equivalent to purchasing multiple copies of a single title). For example, if a library acquires a title with rights to a single user at a time, then that item is counted as 1 “unit”; if the library acquires rights to a single title for 10 simultaneous users, then that item is counted as 10 “units”. For smaller libraries, if volume data are not available, the number of titles may be counted.
Unlimited simultaneous use: units of acquisition or purchase is based on the number of titles acquired. For example, if a library acquires a collection of 100 books with unlimited simultaneous users, then that collection would be counted
