Torah Musings Thinking About Jewish Texts and Tradition 
R. Gavriel Zinner has published dozens of volumes in his Nitei Gavriel series of thorough collections of sources, rulings and customs on halakhic themes. His 600+ page volume on Chanukah, originally published in 1983 and revised multiple times, is available for free download here: link

His last name is spelled Zinner (with a Z).
In his haste to publish many works, accuracy has suffered. It’s always good to check up on any sefer which he quotes to make sure his quote is accurate. Also, he occasionally brings a new opinion with the source being “Mesorah”. What sefer is that? Yup, you guessed right. It’s the OU Mesorah Journal quoting Rav Soloveichik.
Shimon S: Thanks for the correction
Kovner: At least he quotes Rav Soloveitchik
I don’t mean to be mean, but his seforim have greater problem than “suffered accuracy”. Therefore, it would be advisable never to rely on the psakim in the sefer and to always look up the sources. More than once I have found sources in there that didn’t say what R. Zinner said it says.
R. Zinner was associated with R. Menashe Klein of Ungvar earlier in his career. At one time he had the title Ungvarer dayan.
u are correct that his haste to publish creates mistakes, but he usually corrects it in 2nd printings
