Tony,
I would probably treat "Here begynneth a lytell treatyse called" as Introductory words.However, "Here begynneth a lytell ..." was once used quite often to start a title in publication, and as a cataloger, you have to treat them on a case-by-case basis. The wyse chylde of thre yeare olde itself is a complete title without those introductory words, but in the following example: /Here begynneth a lytell treatyse of the horse, the sheep, and the ghoos, /the "introductory words" are more integral to the title than in the previous title. So sometimes it is a cataloger's judgement call, I guess.
Good point.
2. Three books of occult philosophy (http://lccn.loc.gov/92033147) I would still do the same. This is a collective title.
I believe it's not a collective title here in the sense of "Three novels", i.e. it's not a collection of three different works. In Latin it's "De occulta philosophia libri tres". So it's only one work, with the text being divided into three books.
My feeling was that the "three books" could be seen as "not intended to be part of the title", as the statement only gives the extent. And as the phrase comes at the beginning, I thought that 2.3.1.6 might apply here. But I see now that it is indeed debatable whether they are "introductory words". We should better transcribe statements of extent at the beginning as part of the title.
