Book collection database plugin???

Hello everyone,

I wonder if any of you have found, used or have tested any WordPress plugin which helps one to make a collection database with advanced query possibilities.

I have made a site to my friend. The site concentrates to quite large collection of printed articles and books about fish species, fish economy, biology, sport fishing, professional fishing etc. in Finland.

You can see the site here (the site is written only in Finnish language): http://www.suomenkalakirjasto.fi and the database that there is at the moment based on the Obvibase: https://www.obvibase.com/p/Q4NPOj8zmYST#table/Q4NPOj8zmYST/*

The site’s owner would anyway like to have a book library like they do in OpenLibrary (https://openlibrary.org) with advanced search options.

The very first requirement is that it has to be possible to import data from cvs -file (like in Obvibase). My friend has an excel file that consists over 22 thousand items at the moment, so no-one would seriously start to add the items one by one to database.

Earlier I found Web Librarian plugin (https://ww.wp.xz.cn/plugins/weblibrarian/). It is just what we want but there was certain problems when importing cvs -file. And also Web Librarian had some problems in handling book’s publishing time. There was also some issues with ISBNs: the books there are in my friend’s collection starts from 18th century, and obviously there were no ISBNs that time.

I am very grateful with any help.
