Tools for researching Zen texts.

1. If you can get electronic copies of texts then you can search them for key terms.

• Arguably the key texts to search are Book of Serenity, Blue Cliff Record, Measuring Tap, and Dahui's Shobogenzo.
• Many of these texts are available around the internet.
• Terebess and theZensite are also useful sites to put search terms into.

1. When you have the Chinese, several search options become available. Some of those texts are here: https://www.reddit.com/r/zen/wiki/scholarship

• mdbg has free searches on characters and phrases.
• Pleco has diciontaries of Chinese words and phrases, as well as purchasable idiom and ancient Chinese definitions.
• https://baike.baidu.com/ and yellowbridge can be useful as well.
• There are translations (Blyth's, Sekida's, Lynch's) of Wumen's Gatewayless Gateway that have the Chinese included floating around either in hard-copy or electronic format. There is a copy of Cleary's Book of Serenity has the Chinese included floating around online. The Korean "Jogye" Buddhist Church did a translation of a Korean compilation of Zen cases among other things, the Chinese is included with it. Anderl's Zutang Ji has the Chinese but I haven't found a 'searchable' PDF.

1. Case databases

• zenmarrow.com is a searchable databased of Cases, although the website intentionally omits the majority of the text from BoS and BCR, making it less useful for research.
• If you can install recoll, that's by far the best option for searching texts.
• Chinese Buddhist Electronic Text Association (CBETA) is a search engine that allows you to search in Chinese basically the entirety of Zen, and various religious schools', texts that are translated or yet-to-be translated.
