 **Description of the dataset**
 
 This is the November 16, 2023 snapshot of the English subset of the Project Gutenberg corpus (containing 56712 documents in total), downloaded and preprocessed with code from [this repository](https://github.com/eminorhan/gutenberg).
 
-The data is divided into ~14.2M records consisting of a few paragraph long chunks of text (each chunk is at least 1024 chars long) and the corresponding metadata info. This is ideal for generating fine-grained embeddings of the texts.
+Two different versions of the data are provided: 
+
+* The `chunk_size_1024` version divides the data into ~14.2M records consisting of a few paragraph long chunks of text, where each chunk is at least 1024 chars long, and the corresponding metadata info. 
+
+* The `chunk_size_2048` version divides the data into ~8.2M records consisting of a few paragraph long chunks of text, where each chunk is at least 2048 chars long, and the corresponding metadata info. 
+
+This dataset is ideal for generating fine-grained embeddings of the documents.
