This "publication" is a virtual entry to link in one place all the dances known or thought to have been collected (or just taught) by <<ddp:MacNab, Mary Isdale>> and which have been catalogued on the London Branch archives at <<https://www.rscdslondon.org.uk/macnab>>.

The London Branch list assigns a catalogue number to each dance in a few groups according to where they were published (or not) and the state of information about them.  
_S01-S29_: The nine sets of dances published by the RSCDS. Here numbered 1-29  
_L01-L11_: Eleven other dances published privately or by the RSCDS (here 31-41)  
_F01-F12_: Taught by Mrs MacNab at festivals but not collected by her (51-62)  
_T01-T16_: Typed descriptions from Hugh Thurston/Tom Flett/Elizabeth Sutorius and others (71-86)

Note that not all the dances in the F series yet have entries in the database. The London Branch catalogue continues with other progressively more speculative sets with even fewer database entries.
