|
|

|
A bibliography item in a bibTeX database, based on a dictionary of
|
||
|
|
strings to values. It is parameterized by a symbol `S` giving the
|
||
|
|
type of the item (`:article` etcetera). A `b::BibItem` supports
|
||
|
|
`b[key]` access to retrieve the data and in general acts like
|
||
|
|
a dictionary from `String` to `String`.
