Concrete : microstructure, properties, and materials / P. Kumar Mehta, Paulo J.M. Monteiro. (OCLC #879384979)

Some ebook platforms, particularly those that have formatted text instead of page scans, do not provide a traditional title page/verso to catalog from. It can also be difficult to determine the extent of the book in pages, and the presence of certain elements such as illustrations, bibliography, and index. These may also vary from platform to platform for a given title, which is a problem when you are trying to create a provider-neutral record that accurately represents them all, while only having access to one.

One way to avoid biasing the record to your available platform is to base the description (pagination, etc.) on an available print record for the title, and record this decision in a note like:

588 __ ǂa Description based on print version record.

Note that 588 is not used to indicate where you found individual elements; those notes still go in a general 500:

500 __ ǂa Title from disc label.
