[Avodah] eruv

[Simon Krysl]

Dear all,
can you suggest basic literature or other resources (ie. secondary
sources) on the problematic of building eruv reshuyot, on what the
contemporary halakhic judgments are? I have realized I do not have the
knowledge to have an opinion or to fully understand the controversies
that often arise in this context.
I apologize if this is a too basic question.
Sincerely,
Simon Krysl
