Given the  current scope note for 150 Large type books, it would also be correct to assign "650 0 Large type books" to an instance of such books. Coding 008/23=d (Form of item=large print) could also be useful in some systems and less ambiguous than using the 650.

My understanding has been that LC practice is to add a subfield to a heading like this when it's used for the topic, e.g., 650 0 Large type books $v Bibliography, which provides a measure of disambiguation regarding which sense of the term is being used.

LC's bib catalog includes 1377 instances of the unqualified heading (the first 150 of which all appear to be instances), so they do include large type books in their collection.

I would have also liked to see "Young adult fiction,"  "Picture books for children," and "Readers (Elementary)" established as forms.

None of these terms are eligible for LCGFT because LCGFT is meant to be strictly a genre/form vocabulary.  Aspects such as audience are out of scope for LCGFT.  The new field 385 was created to record the audience aspect, and 386 the creator/contributor aspect (*Librarians'* writings; *Mexican* poetry). These fields will be used in conjunction with genre/form.  So, for a young adult novel, you will record:

385    Teenagers $2 lcsh
655 _7 Fiction. $2 lcgft

For Librarians' writings, you will record:

386    Librarians $2 lcsh
655 _7 Literature. $2 lcgft

For Mexican children's poetry, you will record:

370    $c Mexico $2 naf
385    Children $2 lcsh
386    Mexicans $2 lcsh
655 _7 Poetry. $2 lcgft

Actually, LC is developing a new demographic group vocabulary, LCDGT, which will be used in the 385 and 386 fields.  Until that vocabulary is available (by late spring or early summer), you can use other controlled vocabularies like LCSH as shown above.  Please also note that the 370 field is not yet implemented in the bibliographic format, but I presume it will be available whenever OCLC implements the latest MARC 21 updates.  For further background on the 385 and 386 fields, you can view the MARC 21 proposals at and  For more info on the new LCDGT vocabulary there is an announcement in the LC 2014 Midwinter ALA Update at (search for the word "demographic" to get to that section).   You can also Google LCDGT and see various presentations by Janis Young from LC about it.

As stated before, Large print books was not included in LCGFT because it refers to the manifestation and not work/expression.  Manifestation attributes are not in the scope of LCGFT (although there are a few current exceptions in LCGFT that are not meant to serve as precedents).  Because manifestation form terms found in LCSH are not going to be in LCGFT, I believe it will continue to be correct to use LCSH in 655 with second indicator value of 0.  The only down side to this is that there will not be a genre/form authority available to validate such terms.  They must be validated against LCSH without flipping the MARC coding from 655 to 650.
