Welcome Morbus:For Koha, you can always reach "add book" (Koha >> login >> Catalogue >> Add biblio >> add empty biblio) once.
* they cater to library-installations only (as they should,Yeah, Koha et al are largely over the top if you looking for a system to manage your private collection.
but Koha, for instance, forces me through about five to
twelve screens before I can add one item. I don't care
about ordering, acquisitions, or budgeting - I just
want a "proper" [1] database).
Then create a bookmark on the address.
Then, with the bookmark, you can reach MARC editor in 1 clic.
You will say : "hay, but i still need to login. And i don't need login".
I'll answer => ok, go to : Koha >> Parameters >> System preferences >> insecure >> set to "1" (or "yes", not sure),
and it's done => no more auth check :-)
And you have a nice GUI to create your biblios (and a highly customizable one !)
And for the price, you have a tool that has many new features coming in the near future (in OPAC & librarian).
