How do I create a collection?

Newbie here.

I see that there is a tab titled Collections associated with a composer. How do I add an entry on this page for a new collection?

I have also seen a "work" titled something like "Fantasias for two viols" on a composer page; the page associated with that link contains several multi-part pieces, separated by an editor, publisher, etc block. How are multiple works entered on a single page?

Welcome!

Anywhere in the general information section towards the bottom of the page you just need to add the line:

|Page Type=Collection

Normally each of a composer's works goes on its own page, so collections are only used for scores containing two or more works that can't easily be split.

I have also seen a "work" titled something like "Fantasias for two viols" on a composer page; the page associated with that link contains several multi-part pieces, separated by an editor, publisher, etc block. How are multiple works entered on a single page?

They shouldn't be!
Those pages were only created on a temporary basis when a lot of files were moved to IMSLP from a sister project, with the intention that they should be split up as soon as the opportunity allows.
